Turbine Stand

Modeling

public/stand_iso.jpgpublic/realstand_iso.jpg

The turbine stand was modeled using SolidWorks. Some features of the stand are it's design with ease of assembly and portability in mind. The stand is constructed of schedule 40 steel pipe available at any local hardware store, where they also cut and thread the ends at no extra cost. The outcome of the materials chosen result in an easy to assemble system by simply threading the mast together and pinning the legs on. This allows the ability to quickly disassemble or reassemble the system, as well as the ability to transport it in pieces on foot around campus.

The turbine mounts on 1-1/2" schedule 40 pipe, but to save weight for raising the mast, 1-1/4" galvanized steel schedule 40 pipe was used in the mast. In conjunction with a 1-1/2" to 1-1/4" reducer and 1-1/2" nipple at the top of the mast we adapted it to the proper mounting size. There is also better availability of 1-1/4" fittings in local hardware stores than 1-1/2".

The base of the stand was designed to be made out of a small steel plate to bolt the mast flange to, and four (4) sections of channel welded together. The leg sub-assemblies simply pin into the steel channels of the base using two (2) 5/16" safety pins each. The bolts that attach the galvanized flange to the base plate will be permanently bolted in place; the mast will be threaded into the flange each time the system is assembled.

The legs are made using 1-1/4" black iron schedule 40 pipe to increase the weight of base to prevent tip-overs. The guy wires permanently connect to the end of each leg through a hole using two (2) wire clamps each. The other end of each guy wire will have a hook to attach to the flange on the mast above the coupling, and removed each time the stand is disassembled. By pinning the end of the leg first, hooking the guy wire, then using the leg as a lever to tension the wire and installing the second pin through the leg, no tensioning mechanisms are needed for the guy wires.
